COMBINED STEP-LADDER AND JACK.

SPECIFICATION forming part of Letters Patent No. 624,037, dated May 2,1899.

Application filed August 23, 1898. Serial No. 689,339. (No model.)

To all whom, it may concern.-

Be it known that I, DANIEL HUGHES, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and usefulImprovements in aCombined Step- Ladder and Jack, of which the following is aspecification, reference being had therein to the accompanying drawings.

The object of my invention is to construct an improved form of combinedstep-ladder and jack which may also, when occasion requires, serve as abench, the invention residing principallyin the construction of theparts, which enables the user to readily convert the article from oneuse to another.

In the accompanying drawings, Figure 1 is a perspective view of acombined step-ladder and jack constructed in accordance with myinvention ,illustrating the position of the parts when in use as astep-ladder. Fig. 2isa side view with the parts adjusted to form a jack.Fig. 3 is a longitudinal sectional view of a portion of the same, andFig. 4 is a detached perspective view of'a detail of construction.

Referring to the drawings, A represents the sides of the ladder,atheusual steps, and B the rear supporting-legs, pivoted to extensions 1) ofthe ladder sides. The extensions are provided with pins 0, which fitinto slots 0 in the legs, to permit a slight longitudinal movement ofthe latter for a purpose described hereinafter.

On the inner sides of the legs B are secured projecting plates cl, andextending across the ladder and secured to these plates are flat platesd of a width about equal'to the distance between the steps of the ladderand adapted to fit between the same when the device is used as a jack orbench.

Pivoted to the legs B near their upper ends are bars 6,carryingaplatform e, such as are common to step-ladders; but in thepresent instance this platform is supported by diagonal brace-bars f,which may be secured to the legs either in the position shown in Fig. 1or in that shown in Fig. 2, a thumb-screw g being employed in order tofacilitate ready adjustment to either position.

To the inner sides of the legs B are secured pivot-lu gs h, to which arepivoted j ack-legs h,

the opposite ends of which are inclined, as shown, sothat they maysnugly fit against the rear of the legs and the outer face of a wallbelow a window-sill, as shown in Fig. 2. To these legs are pivoted bars1', connected at their outer ends to links m, which are held to thesupporting-legs by thumb-screws n, the latter being adjustable in slotspin the sides of the legs, so that by adjusting their positions the lowerends of the jack-legs can be raised and lowered to suit the wall orwindow. The bars 2' are hooked at t", so that they may engage on thewindow-ledge,as shown in Fig. 2.

WVhen the device is to be used as a ladder, the parts are adjusted asshown in Fig. 1. To form a jack, the bars f are adj ust-ed to theposition shown in Fig. 2. The parts A and B of the device are pressedflat together, so that the plates d Will enter between the steps, thisbeing permitted by the slotted connection 00', which allows of slightlongitudinal movement of the part B,so thatsaid plates dmayenter betweenthe inclined steps. The plates d will form a flat level surface, asshown in Fig. 3, on which a man may stand. The jack-legs h are thenturned down and the hooks i engage on the window-ledge. The device isthen looked in position by properly adjusting the screw 0?. along theslot 19.

When used as a bench, the parts are arranged as for ajack, and the legsh and bars 6 form supports for the said bench.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination,inacombined step-ladder and jack, of the laddersides, the steps, the legs pivoted to said sides, plates carried by saidlegs and adapted to fit between the steps when the device is folded, aplatform pivoted near the top of the legs, and a brace pivoted to saidplatform and adapted to be secured to the legs at a point either aboveor below said platform, substantially as specified.

2. In a combined stepdadder and jack, the combination of the laddersides, the steps, the rear supporting-legs having a pin-and-slotconnection with the sides, plates carried by said legs and adapted tofit between the ladder-steps, a platform carried by said legs,

jack-legs pivoted to the supporting-legs, and bars L connected to saidjack-legs, links m hook-bars carried b said 'ack-legs substanpivoted tosaid hook-bars and an ad 'ustablc 3 J 1 tially as specified. screwn forconfining said links, substantially 3.
